论文摘要
我们通过实验证明了基于偶极极化的电场传感器。我们通过改变极化子的偶极力矩来调整和优化传感器的灵敏度。我们表明，Polariton交互作用在确定最佳电场感测条件并达到0.12 V-M $ $^{ - 1} $ - Hz $^{ - 0.5} $的灵敏度方面起着重要作用。最后，我们应用传感器来说明极化子的激发会在空间区域中修改比光激发点大得多的电场。
We experimentally demonstrate a dipolar polariton based electric field sensor. We tune and optimize the sensitivity of the sensor by varying the dipole moment of polaritons. We show polariton interactions play an important role in determining the conditions for optimal electric field sensing, and achieve a sensitivity of 0.12 V-m$^{-1}$-Hz$^{-0.5}$. Finally we apply the sensor to illustrate that excitation of polaritons modify the electric field in a spatial region much larger than the optical excitation spot.
